A home is a place of residence or refuge.When it refers to a building, it is usually a place in which an individual or a family can rest and store personal property. Most modern-day households contain sanitary facilities and a means of preparing food. Animals have their own homes as well, either living in the wild or in a domesticated environment. "Home" is also used to refer to the geographical area (whether it be a suburb, town, city or country) in which a person grew up or feels they belong, or it can refer to the native habitat of a wild animal. As an alternative to the definition of "home" as a physical locale, home may be perceived to have no physical definition—instead, home may relate instead to a mental or emotional state of refuge or comfort.There are cultures in which members lack permanent homes, such as with nomadic people.
